ToaZZ whom #may concern:

Be it known that I,r GEORGE E. Dyna, .a

citizen of the United States, residing at Kansas-City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Auxiliary.` Lever Attachments for Jacks, of which the following is a specification. Y

My invention relates to lifting jacks of that class designed for placement beneath the axles of an automobile for thel purpose of raising the same, and my object isto provide an auxiliary lever attachment whereby the jack may be placed in position i accompanying drawing, infwhich:

Fig. 1 is a side elevation of a lifting jack equipped. with the attachment.

Fig. 2 is a plan view thereon The lifting jack 2 may be of any ordinary construction embodying a base 4,a standard 6, and a lifting rack 8, `which lis actuated by the usual main lever 10 `removably held by suitable means such as a bolt 13 in the socket 14 ofvaiiy suitable lifting and holding means mounted in the standard 6.

, Referring n now more particularly to the j attachment constituting the present invention, 16 kdesignates a bracket consisting of two members firmly clamped to the standard G` at a point below the socket `14 .by suitable means such as bolts 18. n l

20 designates an auxiliary lever of suitable length and `consisting of a pair of sections 22 and a section24. The section 24 isconnected to the sections 22 by a pivot 26 inl order that ity may be folded lbeneath said secs tions 22 whennot in use. When the section 24 is extended for use it is secured in such extended position by thetpivot 26 and a bolt 28.v Tlie'pair of sections 22 are fulcruined upon the bolt 18. g v

32l designates a pair of connecting bars having a plurality of holes 34, so that they may be adjustably connected to the lever sections 22 by a bolt 36. rIhe connecting bars 32 extend upwardly from the lever sections 22 andare united at their upper ends l ent, is:

a spindle 40` upon which an aiitifiiction l roller 38is'mouiited. i v -The connecting bars 32 are held at substantially right-angles to the lever sections 22 by a pair of links 42 connected `to the spindle 88 and a pivot 44, which latter is se-` cured Vto the bracket 16. The links 42 are provided at their upper portions with pivotally mounted arms 46 carrying a spindle 48 upon which an antifriction roller 50 is journaled. The roller' 50 is yieldably held against the underside of the inain lever 10 by coil springs 52 connected vattheir ends vto the links 42 and the arms 46.

In practice the outer end of the lever 10 is arranged between the rollers 38 and 50, and the auxiliary lever 20 is extended as shown by Figs. land 2. When thus extended the jack can be placed beneath the front or rear axle of an automobile and actuated to raise V,the same while the operator is in a standing position. As the auxiliary lever20 is swungup and 'down on its fulcrurn 18, it,`

through the iiiterinediacy of the connecting bars 82 and rollers 38 Vand 50, moves the main-lever ll0 up land down. It is obvious that the main lever lOcould not be swung up and downan appreciable distance if the rollers 38 andV 50 were fixedly held .in contact therewith, owingto the oblique angle which said mainlever 10 assumes to the connecting f bars 32, but by yieldably. mounting the roller 50 as liereinbefore described `said main lever 10 InayL swing freely without being checked by said rollers 88 and 50. After the operator gets through with lthe jack the main lever 104 may be removed and the sec Y tions 22 swung upwardly adjacent to the.

rack 8 while the section 24 is folded against said sections 22 sortliat the jack may be packed away in a tool box.

From the foregoing description, taken in connection with the drawing, it is apparent that I have provided an attachment for lift-V ing jacks embodying the advantages aboveV pointed out, and while I have shown and dei i scribed the preferred construction, combination and arrangement of parts, I reserve the rightjto niake such changes and modifications as properly fall within the spiritk and scope of the invention as claimed.

' I-Iaviiig thus described iiiy invention, what I claim and desire to secure by Letters Pat- 1. The 'combination with a lifting jack having actuating iiieaiis including a main g I Y 1,575,046

lever',V of av bracket secured; to the standard of said lifting jack, an auxiliary lever pivotally connected to said bracket, connecting bars extending upwardly from said auxiliary lever and operably connected 4to the main lever, and links pivota-lly' connected: tothe upper portions. of said connecting bars and of Said lifting jaekl, an auxiliary lever piyotally connectedl to said bracket, connecting lever and operably connectedV to the main lever, links pivotally connect-ed to the upper portions of said connecting bars and the bracket, a vroller engaging the upper surface of the inain lever and mounted on the pivot connecting the links'and the connecting' bar, aroller engagingthe underside of the main lever, a spindle on which said roller is journaled, ai parir of" arms carrying sai-d spindle at one end and pivotally connected at their opposite end tothe' linke,y and Spring nieans connecting saidarms and theL links to yieldably hold the last mentioned roller in engagement' with the vIna-in lever; bars extending upwardly roin sind auxiliary In' testimony Wl'ieiieof Il amr my signature.
